So here is case,I have a main Page with aViewPort and one panel in west region wich contains a treepanel that is loaded from data base,I also have a tabpanel in center region.When nodes are clicked they make a new tab to be added in tab panel and load some url inside of them.The problem is that these new pages that are loaded in tabs can make changes in the database and I want to Update my treepanel when changes are made.Does any one have any suggestions?Ive searched in forum's topics but couln't find any ideas.
